Industrial vehicle with optical lift height measurement

摘要

The truck has a lifting gear (14) comprising a lifting frame (20) attached to a vehicle frame and a lifting arrangement moved relative to the lifting frame in a vertical direction (V). A measuring arrangement detects a movement of the lifting frame and/or the lifting arrangement relative to the vehicle frame in a contact-less manner. The measuring arrangement has optical sensors (32) for sampling a random surface configuration of the lifting frame and/or the lifting arrangement. The sensors are fastened at the lifting frame and turned towards an upper surface of the lifting arrangement. An independent claim is also included for a method for lifting height determination of a lifting gear of an industrial truck.
